Oxidized Insert Bearing OUC207-20 BLACK BEARING

GJP OUC207-20 is Black oxidized insert ball bearing normal duty insert bearing with set screw locking insert bearing and a wide inner ring

To meet the difficult operational requirements of the wind turbine industry, we are using a special process called black oxidation. it gives bearing components a protective layer that is chemical and corrosion resistant and helps prevent bearing damage during the crucial running-in phase.

Black oxidation process

Black oxide is a surface treatment that is formed by a chemical reaction at the surface layer of the bearing steel and is produced when parts are immersed in an alkaline aqueous salt solution operating at a temperature from approximately 265 º F to 300º F. The reaction between the iron of the ferrous alloy and the reagents produces an oxide layer on the outer layer of the bearing components, consisting of a well-defined blend of FeO, Fe2O3 and resulting Fe3O4. The result is a dark-black surface layer of approximately 1–2 μm in thickness. The total process consists of about 15 different immersion steps, in many of which it is possible to vary chemical contents, concentrations, temperatures, immersion times and fluid behavior within the tanks

GJP is a professional oxidized insert bearing exporter, we have many years of export experience, the main export countries are USA, European country, Asian market and Middle East market.
